Common Types of Body Fossil Preservation. 

Specimens are all around us; they are the plants, animals and minerals that make up the world we live in. They form our understanding of Earth and inform humanity’s role in the environment. These natural collections represent our planet’s diversity at a particular place and time. Learning to ‘read’ a specimen is a skill to be acquired through practice, just like reading a book. Specimen observations help teach us how to really look at an object and make inferences! Some questions you ask of any natural specimen are included in the document below.

Trilobites are the earliest known arthropods.  Their fossil record spans from the early Cambrian (~521 million years old) to the end of the Permian (251 million years ago), but they are not very common after 372 million years ago. Trilobite bodies have a cephalon, segmented thorax, pygidium, and have compound eyes. They are only found in saltwater environments.

Proetidae is a family of Trilobites that are found from 485 to 251 million years ago.
